php - How to stop preg_replace() returning numerical references? -


i'm using preg_replace() perform regular expression search , replace.

$string = "this isn't real string example."; $result = preg_replace($pattern, $replacement, $string); echo $result; // isn’t real string example.

as can see, $string contains single quote. regardless of whether match found, when output return value of preg_replace(), single quote becomes ’

how can stop preg_replace() returning numerical references such ’? need string keep single quote character.

update

here's pattern:

$pattern = '/#(\w+)/';

update 2

here's replacement string:

$replacement = '<a href="https://example.com/tag/$1/">#$1</a>';

you can try using html_entity_decode() achieve that

here snippet 

$string = "this isn't real string example."; $result = preg_replace($pattern, $replacement, $string); echo html_entity_decode($result); // isn't real string example.
